XD6123/XD6124^Series

☆AEC-Q100 Grade3

Voltage Detector with Watchdog Function and ON/OFF Control

■GENERAL DESCRIPTION

The XD6121/XD6122/XD6123/XD6124 series is a group of high-precision, low current consumption voltage detectors with

watchdog functions incorporating CMOS process technology. The series consist of a reference voltage source, delay circuit,

comparator, and output driver. With the built-in delay circuit, the series do not require any external components to output

signals with release delay time. The output type is VDFL low when detected. The EN/ENB pin can control ON and OFF of the

watchdog functions. By setting the EN/ENB pin to low or high level, the watchdog function can be OFF while the voltage

detector remains operation. Since the EN/ENB pin of the XD6122 and XD6124 series is internally pulled up to the VIN pin or

pulled down to the V_SSpin, these series can be used with the EN/ENB pin left open when the watchdog functions is used. The

detect voltages are 1.6V, 2.2V, 2.3V, 2.4V, 2.9V, 3.0V, 3.1V, 4.4V, 4.5V, 4.6V, using laser trimming technology. Six watchdog

timeout periods are available in a range from 50ms to 1.6s. Five release delay times are available in a range from 3.13ms to

400ms.

Characteristics

Output Configuration

Watchdog Pin

: N-channel open drain

: Watchdog input

If watchdog input maintains ‘H’ or

‘L’ within the watchdog timeout

period, a reset signal is output

from the RESETB pin.

: When the EN/ENB pin voltage is

set to low or high level, the

watchdog function is forced off.

: 400ms, 200ms, 100ms, 50ms,

3.13ms (TYP.)

EN/ENB Pin

Release Delay Time

Watchdog Timeout Period

: 1.6s, 800ms, 400ms, 200ms,

100ms, 50ms (TYP.)

Operating Ambient Temperature

: -40℃~ +85℃

: SOT-25

: EU RoHS Compliant, Pb Free
